Application filed August 23, 1912. Serial No. 716,578.

a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ghio, have vinvented certain new and useful Improvements in Cash-Regis ters, of-Whieh l declare the following to be a full, clear, and exact description.

This invention relates generally to accounting machines and thel particular embodiment shown and described to that class known as cash registers which employ indicators for indicating the Aamounts entered in the accounting mechanism.

The objects of the invention include the provision of an improved form of a differential mechanism in -which the actuators always move in the same direction, as distinguished from the well known oscillatory or reeiprocatory types. ln the particular embodiment shown the actuators of the differential mechanism have constant extents 'of movements at 'all operations, but their various points to control their extents ofmovement which take place while the accounting mechanism is in condition for operation by them.

The objects also includethe provision of improved indicator actuating mechanism for actuating the indicators from the novel differential mechanism. The indicator actuatingA mechanism includes lioating indicator actuating segments, and cams rigid with the actuators of the differential mechanism to differentially control. the movements of the same and thus the setting of the indicators. This mechanism is not claimed herein, however, but forms the subject matter of a divisional application Serial No. 38,639 filed July S, 1915.

Another object of the invention is to con struct counter mechanism and transfer mechanism therefor, well adapted for use with the novel differential for actuation thereby and also for controlling the movement of thc differential mechanism in turn to Zero or total taking operations. The counter includes two sets of cilintinuously meshed pinions, one bearing reading characters if desired, and either of which may be brought into engagement with the actuators for ro tation thereby.v the direction of movement of thepinion by the actuators for turn to mechanism zero or item entering operationsA being dependent upon the set of pinions in mesh with the actuators, but in both operations the actuators of the differential mechanism .zero operations those of the one are disengaged from the actuators and rotate in proximity to levers adapted to be operated by the return to zero of the pinions of the one to throw in stops for the actuators. The transfer mechanism includes plates mounted for sliding movement andfwhich carry pawls the tails of which are posi-- tioned behind teeth of the next higher pinions and when stripped by their corresponding pinions passing from nine7 to Zero positions. The plates are `then moved to eifect additional steps of movement of the pinions in the paths of tripped pawls and to restore the pawls to untripped positions after transfers have been effected.

Still another object of the invention is to provide locking detents for the keys which serve not only to lock the keys in depressed position, but the unlocking movement of which detents serve also toV positively restore depressed keys.

lVith' these and incidental objects in Viewv the invention consists in certain novel features of construction and combinations of parts, the essential elements of 'which are set forth in the appended claims, and a pre-- ferred formr of embodiment of which is hereinafter described with reference to the drawings which accompany and form part of this specification.

Figure 1 represents a sectional view of the machine taken at the side and looking in the direction, of corresponding units of the differential, indicating', totalizer, and transfer mechanisms. Fig. 2 is a section 'of the keyboard taken Aat the position Vof the fourth key from the top but with this key omitted. Fig. 3 is an enlarged view of one of the banks of keys and some of the eo- 1 perating parts of the operating mechanism. Fig. Il is an enlarged view showing by rotation ofthe driving disks 51, one com- ,plete rotation ofwhich in a counter-clockwise direction takes place at each operation ofthe machine, and when the inner por tions 50 of these dogs are so located in the notches 52 their `outer angular noses 58 will lclear the notched plates 220 and permit counter-clockwise movement of the actuator gears 40 with their dogs 38 and spiders 45,

vby the driving disks 51. The keys when depressed are adapted to project into the dogs engaged by the keys outwardly into adjacent notches 23 of the plates 220. This outward movement of the forward portions of the dogs is sufficient for their inner portions 50 to elearthe notches 52 in which they w'ere located and permit further movement of the disks 51 in a counter-clockwise direction independent of the actuator gears 40 .with the inner portions 50 of the dogs riding on the curved peripheries of the driving disks. The disks continue to rotate independent of the actuator gearsy 40 until those of the notches 52 next behind the ones from which the dogs 38 were disengaged by depressed keys come beneath the inner portions 50 of the dogs 88l adjacent the keys that were depressed, but which in the meantime have been restoredto undepressed positions by mechanismv hereinafter described. With the keys restored to normal position their ends no longer interfere with the projections 44 of the dogs 38 and these dogs are then pulled down by the springs 49 into the notches 52 of the disks 51 so that the latter will carry their c'orrespoiiding actuators 40 and dogs 38 to 'bring those of the latter next behind the projections 850 of the bell cranks 8G which, previously to this, have been restored to normal position with the return of the keys to their normal position, into engagement with these projections 850V which projections serve to swing the engaged pawls- 38 and through their spiders their associated ones downwardly to engage the noses 53 of the dogs 38 contacting with the bell cranks 3G into theuppermostl notches 23 of the p'late 22. This outward swinging of these dogs-h' ser-rsl to clear the inner portions 50 of theml from 'the notches 52 in the disks 51 and allow-the completion of a rotation ofthese' disks without further effect upon the actuators'40. l

As shown in Fig. 1, in the normal condition ofthe machine the notches 52 of the disks 51 are separated 60 degrees' from the coperating portions 50 of the dogs 38, thus providing for degrees of movement of the driving disks 5,1 and the drive shaft before any movement is imparted to those of the actuators 40 which may have been freed by depression of keys in their corresponding banks. Seventy-five degrees of movement of the actuators 40 take place before they are stopped by depressed nine keys, and consequently the counter must be in engagement with the actuators 4() from the time these actuators may be picked up by the driving disks. 51 at the 60th degree of movement of the latter until they may beleft by the driving disks at the 135th degree of movement, when the dogs 38 and actuators 40 would be stopped by depressed nine keys. This is provided for by the cam shown in Fig. 7 which controls the rocking in and out of the counter, and from which it will appear that upon :the rotation of the cam in the direction of the arrow (Fig. 5), the counter will start erocking into engagement with the actuators at the beginning of the rotation of the drive shaft, consuming about 15 degrees of movement for completing this movement. The counter is held in engagement with the aetuators until about 135 degrees of movement of the drive shaft has taken place when it starts `to rock out of engagement complet ing its disengagement from the actuators by the end ofv150 degrees of rotation of the drive shaft. From this it will be seen that the counter is in engagement with the actuators throughout the time that'any actuator may possibly be connected with its driving disk 51, during the .first engagement of these elements any actuator in any operation of the machine being always disengaged from its driving disk after the 135th degree of movement of the latter unt-il the actuators are pickedup by their driving disks the second time for movement to "normal position. The counter is always disengaged from the actuators before the latter are picked up the second time by their driv-fY 'ing disks which could never take place before the counters are completely disengaged from the actuators at 'the end of 150 degrees of movement of the drive shaft.

Fig. 5 shows a'cam 54 rigid with the drive shaft D having a groove 55 in its side inper end at 63 to engage over a pin 64 carried by an arm 65 which supports at 66 the lower end of a detent plate 67 for a turn to zero key in the mannerthat the lower arms 28 of the amount key banks support their corresponding detent plates24. The shaft 4 rigidly carries arms 68 connecting with links 69 which in turn connect with the arms 28 of `the amount key banks by pin and slot connections similar to the connections between the linksv (i2 and the arms (S5 for the turn to zero key bank. T he pin and slot connections 63 and (Si permit downward movement ot the detent plates 24 and (i7 independent oi' the links G2 and 69, to allow depression of the keys. lironi the shape oi' the groove in the side of fam it will be seen that the shaft i will be rocked in. a. counter-clockwise direction at about the 150th degree ot movement oit the cam 54, the latter rotating in thc direction oi the arrow shown in Fig. 5. rlhis rocking of the shaft 4 serves to lower all of the links 62 and G9 suliicientlyto engage the upper ends of the slots 63 with the pins 6i and lower the deteiit plates and G7 suliiciently to. releaselany depressed keys and also positively to engage the projections 3l and pins 811 of the detcnt plates with the inclined projections 3l on the upper side of the keys just below them, if such keys were in depressed position, and positively return such keys to normal position. The shaft 4 and the detent plates for the keys are held in moved position until near the end of the operation of the machine when, dueto the shape oit the cam groove these parts are restored to the normal position shown in Fig. 5. By this construction restoration of depressed keys is provided 'I'or prior to the second picking up of the actuators by the driving disks 5l for returning they former .into position for the next operation.

00u-afer (md transfer mechanism/.wits the actuators for the machine have but one di rection of movement, and as it is desired to provide for turning the counter to zero by an operation of the machine, provision is necessarily made for effecting two directions oi2 movement of thel counter elements from the single direction-offmovement of the actuators. To this end the counter pinion's proper are always in mesh with corresponding similarly shaped pinions also car- `ried by the counter irame.

represents one of the counter pinions and7l the corresponding pinion always in mesh with it. 7 2 represents the disks rigid with the counter elements 70 which may have characters from Zero to nine printed on their peripheries if so desired. The shafts 7 3 and 74 respectively carry the counter pinions and disks 7 2 and the corresponding pinions 7].. rIhese shafts are supportedy at their ends by frames which have inwardly bent ilanges7t at the front for cooperating with the shaft G to prevent undue downward movement of the forward portions oi the frame. The counter frames 75 are pivoted at 77 to arms 78 rigid with the shaft 7 which is rocked at each operaftion of theV machine by cam 79 shown in the counter frame carries the latter towardv the actuators at the beinning 'of an operation of the machine and away from the actuators by the completion of 150 degrees of rotation of the drive shaft.

011e of the counter frame pieces '75 is provided on its upoer edge with projections 86 and S7 for cooperation respectively with. arms 88 and 89 of a forked member 90 loose on the'drive shaft. This member 90 is rigid with arm 91 to which is pivotally connectv ed at 92 one end of a link 93, the opposite end of which` is connected at 94 with one arm of a bell crank 95 pivoted at 96 to the frame for the turn to zero key, and the other arm of which is pivoted at 97 to the detent plate 67 for this key bank. `In the normal position of the machine the arm S8 of the -tork 90 is above the projection 86 oi the counter frame so as to limit the movement of the rear side or' the trame toward the actuators eiiected by the rockingof the shaft 7, and the arm S9 of the forked member 90 normally clears the projection 87. Operation of the machine with thc forked member 90 in the position as shown in the drawings, by rocking of shaft 7 and upward movement of its arm 78 carries the counter pinions 70 into engagement with the actuator gears 40 because the arm 88 of themember 9G, by engaging the pro jection 86 of `the counter frame, limits the upward movement of this rear ide of the trame and causes increased movement of the forward side ot' lthe frame and the count-er pinions 7 0I to lengage the latter with the actuators by reason of the arms 7 5 being pivoted at 7 7 between the projections 86 and V87 ot the counter frame. This rocking in of the counter pinions 70 occurs prior to the movement of the actuator gears 4() which, when subsequently moved in a counter-clockwise direction as shown in the drawings, effect rotation of the counter pinions 70 in a clockwise direction and to extents proportional to the movement of the actuators taking place while the counter pinions are engaged with them.` As the counter wheels are always in engage-)mentwith their corresponding pinions 71,;the latter will be rotated counter-clockwise to corresponding extents. Pins 71.1 on the counter frame 75 are just below the ends 712 of the firms 78 and through these pins the arms serve to vpositively disengage the counter pinions4 from the actuators as the' arms are rocked downwardly for this purpose.

This construction. permits however the necessary swinging oi the counter 'frame counter'- cloclrwise about its. pivot 77 for engaging the pinions 71 with the actuators for total takingI operations.

rllranslerring operations between the counter wheels are effected through the pinions 71 which for this purpose carry pins 98 which, as these pinions pass from positions eorrespondirugr to the nine positions of the counter wheels to positions corresponding to the zero positions of such wheels in add.

ingoperations, engage inclined portions 010 of pawls 920 pivoted intermediate their ends at 930 to plates 940 slotted at 95() for workingover stationary .shafts 8 and 9 rigid. with the machine j Alining pawls 960 carried by the plates eoope'ate with notches 9.70 and Q80 of the pawls 920 for respectively holding the latter in untripped or tripped positions. lawls 0S) pivoted at 100 to the plates 9.410 are normallyA held, by springs 101v connected with their lower endsand with plates 940, with their upper ends in engagement with the upper ends of the corresponding pawls 020. The position of these pawls shownv in Fig. 1 is their normal position, while that of Fig'. l is their adding position, and rotation of the pinions 71 one step in the adding direction from. the position shown in the latter ligure serves to force rearwardlythe upper ends ot transfer pawls 92() and sulicient to position notches 102 of the transfer' pawls adjacent projections 103 of the pawls 99 so that under the influence of'spring 101 projections 102% of the pawls 09 will engage in the notch 10?l and, 'retain the transfer pawls 020 in tripped positions. T his .tripping of the transfer pawls9'20 carries ytheir tails 104 upwardly behind one of th@ teeth of the next hi gher pinion 71, but not botweenthe teeth ot such pinion lso aste prevent further movement oli' the lat-ter. j

rrlter the movement of the counter pinionel and the pinions 71 effected bythe actuator gears 40 is'cm'npleted and the counter is disengaged from the actuators, the actiial transterrine operations take place. The transfer plates 'il-l0 before the beginning;r of an operation-ot the machine are in the position shown in Fig.. 1 but at the beginningr ot' an o; eration""they. are all simultaneously moved `forwardly and upwardly tothe position shown in Fig. l, reaching su'ch moved position after the proper set of the pinions 70 or 71 is engaged with the actuators, [t is on the return rearward movement ot' the plates after the pinions have been moved by the actuators that the transferring opera tiens take place.

The reciprocation o1 the plates* 0-10 1s brought about by a series of two armed sleeves 105, one less in number than the pinions. 71, arms 10G of which sleeves have 111 slotted at their upper ends at 112 to be engaged over and be guided by the drive shaft D. These links 111 carry rollers 113 projecting from their sides into grooves 114 in the side oi? corresponding transfer cams 115. The grooves oi these cams are oit` such shape and so related to each other as to cause at the beginning ot an operation, the sin'niltaneous loweringr of the links 111 and the consequent forward movement of the plates 0l() to bring these transfer pawls into cooperative relation with the pinions 71 if the latter are in their item entering positionan'd to cause, beginning shortly after the 150th degree of movement of theV cams, the successive raising from lower to higher denominations of these links vand' the corresponding downward and rearward movements of their plates 940. rlhs downward and rearward movement of these plates 010 takes place after the counter 'frame is restored to normal positioin and carries along the pawls 920 and those ot' the pawls which have been previously tripped will have their tails 101- engaged between adjacent teeth of the pinion 71 by the loweringof the pinion 71 to normal position so that the movement of the plates 040 away from the pinions 71 imparts an extra degree of movement to such pinions. lt will. be noted that when the counter is rocked upwardly i'or engagement with the actuators for item entering operations the pinions 71 are also carried slightly toward the actuators to engage the projection H0 ojt the counter frame with the arm 88 of the yolie 90. As the counter frame during this party of' its movement rocks about th* shaft 7 as an axis the pawls '920 will not aliect the pinion 71 because these pawls and their platesllll) are in rear! most position until the pinions are engaged with the actuators, When adding' operations are taking place, at which time the transfer pawls 92 are in position to be tripped, the pinions 71 will be slightly ele rated from the position shown in iig. l to the position shown in liigr. 4i. and when in this slightly elevated position the trij'iping ol the transle' pawls will not carry the tails of the latter in between teeth oi' the pinions 7l adjacent thel ones doing; the tripping7 but only suliicientlv upward .so that when the counter frame is lowered from engaging the counter pinions with the actuators the pinion. 71 will be carried down to locate the tails 104 of the tripped transfer pawls between adjacent teeth oi' their cooperative pinions. This leaves the pinions 71 so that they will be actuated onestop upon the rearward and downward recijrrrocation oi the plates Jil-0 which then takes place, as above described,

ro disable lie n'iinii are nor: sion oi' a lier rear ends of the detent plates for the amount banks do not connect with their arms on the carrying plates 120 to bring their projections into the path of the dogs 38 for'stoppin'g the movement of the actuators the counter pinions 70 carry pins 121 which coperate with the free endsof levers 122 pivoted at 123 to arms 124 rigid with shaft 5. The upper ends of levers 122 are pivoted at 125 to the forward ends of links 126, the rear ends of which are pivoted at 127 to depending arms of sleeves 128 loose on the shaft 10. These sleeves 128 have arms which pivotally connect at 129 with the lower ends of corresponding links 130. the upper ends of which are connected at 131 to the rear arms of bell cranks 132 loose on the shaft 11. The sleeves also have arms 133 and to these arms and the corresponding arms of the bell -cranks 132 are pivoted at 13 and 1135 ref spectively the plates 120, each of which as stated above, has a series of projections 136 ten in number, -for engaging projections 44 of dogs 38 when these members 120 are' moved forwardly to carry the projections 136 into the path of these dogs. y

The shaft 5 carrying the arms 124- has an arm 137 pivoted at 13S to the forward end of a link 139, the opposite end of which is slotted at 110 to engage over and be guided by the drive shaft l). A roller 141 projects from the side ofthe link 136 and into a groove 142 in the side of a cam 143 rigid with the drive shaft. From the shape of the groove 142 the shaft 5 is in all opera tions of the machine rocked at the beginning of the operation in a `clockwise direction and at about 150 degrees of movement of the drive shaft back in a counter-clockwise direction to normal position. While the shaft 5 is in moved position the moven'ient of the actuators 4() will take place and during this time the shaft 5, through arms 12J:A supporting the levers 122, holds the pivots 123 of the latter rearward sufficiently to locate the lower free ends of the levers 122l lrearward in the patlrof pins 121 on the counter pinions when the latter are raised slightly from the position shown to engage the projection S7 of the counter frame with the arm 39 of the yoke 90, in which raised position the counter pinions stay while the' pinions 71 are engaged with the actuators for rotation thereby. The rocking of the shaft 5 at the beginning of the operation ofthe machine does not effect the notched plate 126v4 at the rear of the actuators, as'it only serves to swing the levers 122 about the pivotal connections 125 with the forward ends of the links 126, unless one of the counter wheels is at zero before the operation of the machine, in which case this clockthe pivots. 123 of the levers by the arms 124.`

Wise'lrocking of the shaft will be sufieient4 to engage the plane surfaces 144 on the` free ends of the levers 122 with the adjacent pins 121 of the counter Wheels standing at zero before completion of rearward movement of lThese pins 121 will then limit therearward movement ofthe free ends of the levers 122 and cause corresponding rearward movement of the upper end of this lever 122 and its connected links 126 as the roeking of thearms 124 is completed. In such cases, which occur when counter wheels stand at zero, the corresponding sleeves 128 on the shaft 10 will be rocked in counter-V clockwise direction to move the plates 12() forward lto immediately bring the lowermost projections 136 into the path of ad jacent dogs 3S beforev any movement of the actuators. The latter 4will subsequently have practically no movement until projections tot their rear dogs 38, which at the beginning of an operation of the machine are always in the position shown in the figures, will engage the lowermost projection 136 and be swung thereby outwardlyeffecting through the spiders 46 similariswinging of the two other dogs of the actuators so as positively to hold the uppermost dogs 38 in the upper notches 23 of the plates 220, and prevent theiroperative engagement in the notches 52 of the disks 51 for movement thereby.

ln cases in which the counter wheels are not at zero at the beginning of an operation of the machine, the clockwise rocking of the shaft 5 at the beginning of an operation serves only to carry the lower free end of the levers 122 into the paths of pins 121 on lthe counter wheels 70 when the latter are -of the actuators.

in the paths of dogs 3S and through the projection 136 just above the dog 138 adjacent the plates prevent further movement Engagement of the projections 41 ot'V the dogs 38 with the projections 136 on the plates 12() throughthe dogs and spiders 46 positively throws the noses 53y of the dogs next ahead into the notch 23 of the plate 220 adjacent'it. In this way the extents of movement of the counter wheels to zero positions'serves to disconnect the driving disks 51 from the actuator gears A10 and control the differential movement of the, latter. V,In total taking operations the transiter mechanism above described has no e'itect'upon the counter wheels as the pinions ,71. would not pass positions corresponding tcnot the machine are adapted to he adjusted at each operation ot' the machine in aizci'ndancc with the diiipercntiai movement of the actuators. To this end the actuators are rigid lvrith disks '146 at their side having three siinilariy shaped raised por-tions 11'? on their side in which are out cam grooves 148. Links 156 ti'irongh siots 151 engage over and are guided by the drive shaft and these lat their lower ends carry rollers projecting into the planes of the cam Larom'cs 11S vand adapted to pass through these cam grooves as the disks are rotated.

The upper ends of the links 150 pivotaliy connect at 1532?; with the rear ends of tient ing indicator actuating segments having gear teeth 155 in mesh with pinions 156 loose on the indicator shaft 12 but rigid with not ied alining disksli' and the inv -dicators 11a. rthe shatt 13 passes ieneath the Heating` segments 151 and to prevent their undue movement in d 'nivard direction. Shaft 111 rigidiy car "ies indica.- tor dining parvis 158 for engaging in notoires 159 ot' the alining d""" s tor the ind ir-:nrs and preventing dispiaccment ot the after they have been adjusted. .ilhe alining paivls 158 have arcuate projections 166 beneath the shaft 111v and upon these are pivoted at 161 depending hooks 14.112, the iower portions of which are normalty heid forward by springs 16? connect-H in g,` with rear tails of the hooks and with .eyes on the rear portions of the arcuate proicctions 166.

The springs 163 yieidingiv permit rearward movement ot the hooksbut pins 1611 project from the arcuate projet tions 166 in ifi-ont ot the paivls 162 and prevent their undue forward movement.

The hooks 162 are for cope'ating;` with pins on the side ot the Heating; indica-o` segments.` At the end ot an operatimi of the machine the pins 165 are not iocated in the hooks 162 but instead the hooks are be hind them, as shown in Fig. 1. r1`he :dining shait 1% is, however, adapted to he rocked ciockwise at the beginning of an operation of the machine. through an arm 166 rigid with the shaft, pif'oted at 167 to the upper 111-5 looselyT mounted on the shai't 1Q- near the end ot' a link 168 notched at 169 at its lower end to engage over and be guided by the drive shaft andhaving a` roller 176 projecting from its side into a groove 171 at the side ot' cam 172 rigid with the drive shaft. The shape ot the groove 171 is such that link-168 is elevated at the. veri7 beginning of an operation o1 the machine and is held in such position until the drive shaft rotates about 135 degrees ivhen it is lowered. When the link 168 is elevated the aiining pawls 158 are disconnected from the indicator disks 157 and the indicators are reeto he adjusted. Also when the shaft 1d is rocked for disconnecting the alining paivls from the indicator disks the hooks 162 carried by these pawls are carried forward into the path of pins 165 on the indicator segments. i The drawings show the segments for the indicators at zero position but the pins 1.65 ot the indicator segments, before the beginning ot' the operation ot' the machine, are below the position shown in Fig. 1, and the rocking ot' the .indicator alining shaft 11 carries the hooks 162 above the pin 165 of the indicator(segments.v The ends ot' hooks 162 are inclined and the pins 165 of the segments when the latter are raised will engage the inclines 1735 of these hooks and force them rearward against the tension of their springs 163 until the pins pass above them, when the s' nefs 163 iviii Serve to engage the hooks 1t... beneath the pins 165.

in operating the machine for taking a ,total the total hey only is depressed. This shifts the yoke 90 so that when the drive shaft is rotated the vpinions 7l will be engaged with the actuators instead of the counter pinions T which engage with them vin item entering operations. '.hev engage ment ofthe pinioiis il with the actuators results in the counter pinions 70 being reversely rotated by the actuators when the latter are moved.
